🧵 3D design software for Linux
Anonymous at Tue, 11 Jun 2024 17:09:43 UTC No. 986416
I want to start doing learning 3D modelling since I want to design small accessories and jewelry, mainly the kind of stuff that would be injection moulded.
So, what software should I be using? Blender seems to have a lot of tutorials available but a lot of people also decry it as having an unintuitive interface. It also doesn't seem to be that good for when you need exact measurements, which I'll undoubtedly need to be able to fit in pre-fab components such as snap buttons etc.
AutoCAD is unfortunately Windows only, which I'm not going back to ever considering the dumpster fire it seems to have become since I left. FreeCAD might be sufficient for my needs, but would using a straight-up CAD program actually be good for my use case which isn't really that technical?

that's because Blender modeling relies on keyboard shortcuts a lot and some people prefer button-clicky modeling even though they're slower doing it.

polygonal modeling is a little inaccurate for this kind of stuff
so freecad it is

You can not use polygon modelling for injection molding anon, no mold manufacturer that I know will make you an injection mold from a poligon model

the blender UI is fine, it's very intuitive and easy to learn and troubleshoot. People on this board just hate it so they have something to be angry about.
That said, CAD is better for what you want to do. You could try plasticity, it's a CAD program but a lot less technical. But you're probably fine with freeCAD.

What's wrong with polygonal models in this case?
I have some experience with 2D vector graphics by the way, aren't polygons basically just vector graphics but in 3 dimensions instead of 2?

1. The polygons curve and bend to create shapes. Even if the model is subdivided 10 times these fragments are still there but smaller
2. You don't measure in polygons, you just kinda gauge looking at it.
3. Making holes dents in grooves is much smoother in cad. You don't boolean or model that stuff

So polygon modelling doesn't involve using bezier curves, it's just a bunch of straight lines?

I just checked out a tutorial for Plasticity. This looks way easier to use than Blender or any other polygonal software. It seems kinda like vector graphics but in 3 dimensions.

CAD and modeling programs is like art pencil and compess. You can create robots with Blender/Maya while CAD/Compess will say that’s stupid because science says so.

correct.
>>986442
Yeah, it's very intuitive. It's not ideal for inputting exact dimensions which you'll need for injecting moulding, but it can do it. It might be useful to do the design work in plasticity then bring the models into freecad to set up exact dimensions, tolerances, draft angles etc.
Not sure how useful that workflow would be, the work I do is just artwork and occasional gaming stuff, so I do my hard surface design in plasticity then take it into blender for texturing and refinement. It might be better for you to work exclusively in freeCAD. Try both and figure it out.

What makes Plasticity less ideal for all of those exact dimensions?
Also, any good primers for how draft angles etc work? I'm not gonna be doing any advanced engineering exactly.

It's just not user friendly for inputting dimensions, it's not really a drafting program. It's pretty exclusively about direct modelling, not parametric modelling.
>Also, any good primers for how draft angles etc work?
Not my line of work. I just know you want an angle for pulling your shit out of the mould, but as far as specific considerations for injection moulding I have no clue.
How come you're talking about injection moulding and not 3D printing? That's a pretty specialised and expensive thing you're talking about for someone who doesn't seem to know too much about this stuff.

3D printing is not suitable for mass production, but I'll obviously use it for prototyping.

Moreover, 3D printing is less limited in a way than injection moulding, so anything I design for injection moulding can be 3D printed.
With regards to cost, I'll start out with designing stuff that can be produced using laser cutting and the like, since that doesn't require a huge up-front investment. Injection moulding will have to be for once I get the ball rolling.

Polygon models can't be used to make injection molds.
The machines that cut metal don't work with poly models. Don't make that mistake.
If you need to make a mold for injection molding you need nurb surfaces, that why we use cad instead of blender.

THIS HAS TO BE THE MOST GAY LARP I HAVE EVER SEEN IN MY LIFE.
1) I call bullshit despite never getting a mold made
2) This industry (injection molds) is very small and specialized.
3) From the fact that I know for a fact that there are metal injection molds made based on physically made clay sculpts.... there is no fucken way they will not accept a .blend file.
4)
>b-b-b--b-bb
Then 3D print it (4K resin or more) and ship it to them.
However no one will know until someone actually tries. And getting a professional mold made costs more then a luxury car.
Either way I call 100% bullshit.
>Muh CAD muh CAD
CAD is for fagots.
OP using cad to do anything art related is like torturing yourself.
I know almost nothing about CAD however I know one video where some CAD fag creams himself about doing simple edits that are trivial in blender.
From this alone I deduce that CAD is shit and only for drilling 0.001mm line and a 0.005 hole 0.00001 to the left.
Lets solve this the fun way I made this in blender.
Let the CAD fag do the same, if he can not he is one of the 100s of no skill fagots on this board who shitpost all day.
>b-b-b-b- the dimensions the dimensions
Of what you retarded fuck?
I remind everyone that toys where made in clay physically. You do not need the retardation of
>Muh 0.00000001 nanometer hole is 0.00000000001 nanometer away from this other hole
If you need visualization simply take a picture of your hand or something similar and model with this in the background.
As for precision holes I either bet the company you are paying $$$$$$$$$$$$$ for the mold will do get some retarded CAD monkey to do a simple insert hole at coordinates XYZ or you can do it yourself at any stage of the process.

Modeling anything fun looking in CAD is basically impossible. You will wast your time and creativity with CAD shit. You be better off making it in real physical clay then go to CAD.
>Blender can not... precision
You are a fucken retard!
1) Blender can into precision modeling see

Yes it is not the perfect
>Muh 0.00000001 nanometer hole is 0.00000000001 nanometer away from this other hole
CAD autism however you do not need this level of CAD autism for a fucken hole in a keychain figure!
2) Toys used to be made in physical clay (some still are) and this was turned into IRL professional metal molds.
Every toy from the 80s is made in physical clay and was transferred to a metal mold.
https://www.youtube.com/watch?v=jY3
3) if for some reason the company you are literally paying over half a million dollars will refuse to accept a .blend file you can simply 3D print the figure and ship it to them.
Realistically if we are talking this level of money they fix the problems in house or convert the .blend file to anything.
4)
>Muh under cuts muh muh undercuts
Fake and gay.
4.1) Any problems will be auto fixed if this thing is 3D printed since I doubt a resin print will replicate perfectly the unrealistic pertly sharp polygon model.
4.2) if this level of money is involved then these corporations have people on staff who will fix this for you
https://youtu.be/A8_M_ChD54Q?t=15
Worst case scenario you get some calls from their department where some guy says something like
>Do you really need a internally facing 0.00001mm cavity oriented this way?
>Or can I smooth this out?
PS: metal molds are overkill if rubber can do fine.

5) I know from living that there are 3D models made in Zbrush for toy making and also physical sculptures.
https://www.youtube.com/watch?v=UzJ
(notice in the background https://youtu.be/UzJNEcoCT-o?t=689 )
Also if they fucken accept 3D printed figures or literally physically made figures then .blend files are not a problem. Worse case scenario you need to convert your .blend into whatever zbrush farts out.
This is how toy making looks like:
https://youtu.be/qYoCB0tXvxc?t=277
I bet that CAD fag can not make this simple sculpt I made he will struggle with the ears and be unable to make them look like this. Despite this being a easy thing to make. If the CAD fag fails to do this remember to ignore everytihng he has to say.

I made a drawing on a napkin, I'm sure they can make a mold with my napkin doodle, they just need to convert it to a zbrush file using the napkin importer.

Shit, are you schizophrenic for real?
I said nurbs, not cad, every software that can nurb model it's good for injection mold making.
Get some help or stop posting while taking your homemade HRT, your schizoid ramblings are not even funny.
you are the reason people hate blender.
For the rest of normal anons here who are asking the same question, you need to make a model in nurbs to get a metal mold for injection.
It doesn't have anything to do with blender, most machines don't work with poly models.
If you want to use blender make your model using nurbs.

Cool nurbs is not a program go and model in whatever nurbs shit you like the simple model I made.
If you can not do this you literally lost the argument. And are only loosing harder since this is your #2 post without anything modeled.

What files exactly dose zbrush output? The ones used for making metal molds?

And others like

Are you seriously compering a working 3D model to some retarded napkin drawing? STL is what 3D printers use (most common) whatever Zbrush outputs it can be converted from blender output files. And like explained before if they accept PHYSICAL sculptures they accept 3D printed models and
blender -> STL -> Resin 3D printer
Is the way to go.
>b-b-b-b- poly not perfect and
And you think physical sculpts are you dumb fuck? They literally made all toys in the 80s by creating molds from sculpted objects, sculpted by hand, there are lots of imperfections if you do this, microscopic imperfections.
>b-b-b-b- poly not perfect and
And what the fuck do you think Zbruash is outputting? Try to nurbs model a face you dumb fuck. I seriously wait.
However you can not model, you never modeled you are a LARPING retard who shits up this board and you need to be bullied into suicide.

This board is shit like the rest of 4chan and while you schizo no skill retards hate on blender all day places like r/blender post work all the time. Work that is above your skill level.
You never model, you never sculpt you do nothing in 3D only shitpost how bad blender is. Meanwhile professional Zbrush artists say that blender is OK for sculpting and create things like this in it:
https://www.youtube.com/watch?v=3_-
Blender is comparable to Zbrush while inferior in most advanced areas.
Bulling retards like you is the reason I'm even on /3/ it is amazing how fast you can shut down retards here by saying
POST YOUR WORK!
You will never use blender, you will never use any 3D software, you are a fucked schizo NEET who can not model and will never model.
